UNITED STATES PATENT OFFICE.,

ASA BLOOD, SR., OF NORFOLK, VIRGINIA.

IMPROVED STEAM-HEATING STOVE.

Specification forming part of Letters Patent No. 17,483, dated June 9, 1857.

To all whom it may concern.'

Be it known that I, ASA BLOOD, of Norfolk, in the county of Norfolk and State of Virginia, have invented a new and Improved Pa1lorStove,to be known and used as the American Star Stove, and I do hereby de clare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot reference marked thereon.

In the drawings, Figure l is an isometrieal view of the stove with one ot' the sliding doors and screens removed. Fig. 2 is a plan view, with a part of the stove through the line a: a; removed. Fig. 3 is an isometrical view of a wood-burning grate. Fig. 4is an end viewof Fig. 3, showing lthe grate-bars and shaker. Fig. 5 is a view of the coal or ash box and sitter. Fig. is a plan view of a coal-burning grate. Fig. 7 is a plan view of a grate with hollow eylinder-bars- Fig. S is an end view of the same. Fig. 9 is a view ot a toothed shaker. Fi IO is a view of a toothed shaker somewhat di lt'erent from the one shown in Fig. 9.

rllhe nature of my invention consists in making a stove greatly improved for the purpose of burning wood or coal and heating by the aid of hot air and steam.

To enable others skilled inthe art to make and use my invention, I will proceed to dcscribe its construction and operation.

In the construction of my stove, in- Fig. l, A are the legs; B, the lower chamber for ashes and cinders; C,the ash-pan; I), the ash-sitter; E, the steam and hot-air chamber; F, the handle to operate the ash pan and sitter; G, crank for operating the grate; II, II', and H2, the hollow steam-chambers, two of them, II and H2, being divided by a partition through the center, thus forming two passages in each pillar; I, screen-doors; J, grate with hollow bars; K, angular hollow columns through which pass the holes h for the passage ot the products of combustion into chamber Ii; L, the slide-doors operating in grooves attached to hollow pillars II and II'; L', the top chain ber for containing steam and the products of combustion; `outside of the dotted lines in Fig. I is the steam-chamber; inside of the same is for containing the products of combustion; M, the pillars for the passage ofthe effects of combustion, conveyingit int-o chamber O; M', passage for steam; N, the waterchamber; O, the upper chamber for the pro ducts of combustion to enter and pass through; I), the cap to the stove; Q, the pipe or exitpassage for the products of combustion and the steam; R, escapecocks for letting off the steam; S, funnel-shaped pipe for feeding Water to the chamber N; R', the tube for carrying oft' the steam into the roem or for purposes of cooking', it desired.

In Fig. 2, E is the lower steam-chamber; II, pillar for the passage of steam, H' and I-I2 being divided, each having two passages through it; or instead of two chambers in one pillar I may find it more convenient to use two pillars; K, angular hollow columns for the effects of combustion to pass up into the chamber L; II, the water-chamber; a, tubes passing through the water-chamber and open at both ends to allow the products of combustion also to pass through, thus aiding in the generating of-steam.

In Fig. 3, Il. are the vert-ical bars; 2, the bottom bars; 3, the shaker-bars; 4, the shakershafts.

In Fig. 4, c are the vertical bars; CZ, the shaker; (7.', bottom bars shown in dotted lines; (Z2, the shaft.

In Fig. 5, c is the ash-pau; f, the coal-sitter; f', the sitter-handle.

In Fig. 6, g is the bottom plate; h, the bar,

l forming the bottom et the grate; 1', the shaker;

z", the shaft.

In Fig. 7,j are the bottom plates; k, tubular bars; Z,the shaker; Z', the shaft.

In Fig. S, m are hollow bars of grate; a, the shaker; o, the end of rock-shaft, on which the shaker operates.

In Fig. D is a side view of the shaker.

In Fig. 10,22 is the toothed shaker; q, the eccentric crank to operate the grate.

In the operation of my invention the water to be converted into steam is conveyed into the water-chamber N through the receiving-tube S, which tube passes down nearly to the bottom of the chamber, thus conveying the cold water directly to the bottom of the chamber, and also to prevent the escape of steam through the tube. The steam in water-chamber N enters through a tube shown in dotted lines into pillar M', then through tube seen in red lines int-o pillar H', following the direction of the arrows passing into chamber E, filling said chamber as far as the dotted line in said chamber, then up pillar H into chamber L', filling said chamber as far as the partition seen in dotted lines above pillar H2, then down one side of said pillar into chamber L, filling said chamber as far as the partition 2 in dotted lines, then up the other side of said pillar into chamber L' and down pillar I I' again into chamber E and up pillar H', through the tube in dotted lines into pillar M', and the tube in dotted lines in chamber O and pipe R, when it is let o by t-he stop-cooks into Vpipe Q, or it may be carried off into the room for other purposes. The tube R has an orifice in it seen in dotted lines. A tube is seen at a', Fig. 1, extending from the grate into chamber E for conveying the steam or what parts'of it may become condensed into the hollow grate; then passing through it, it passes out of the tube R' in the orifice in the said tube into pillar H', and is carried off, as described. The steam taken from the stove either at R' or R can be used for cooking purposes or for bathing by attaching a conducting-tube to-either of them. The products of combustion pass up the angular fianges K, through holes h and tubes a, into the inner portion of the chamber L', then through pillars M into chamber O and thence through the pipe Q and is carried off.

In the operation of my grate I can easily displace one and insert another when I Wish to burn wood or coal in the same stove. The shaft o in Fig. 8 has a slot, into which the tcnon on the end of the shaft to which the crank q in Fig. lO is attached 'slips into the slot, and thus forms a permanent attachment. To make this connection,it is only necessary to bring the crank and the shaker in a vertical position, and then the grate can be lifted out and another set in. By means of the shaker'bars in Fig. 10,0perating on an eccentric, they have an uplifting movement, passing easily up into the coal and lifting it up, causing the ashes to fall into the sitter.

By means of the sifter in the ash-pan I am enabled to sift the ashes from the coal and preserve the coal and cinders, this being done inside of the ash-chamber, which fits tightly and does not allow any of the dust to enter the room.

In the operation of my slide-doors when I rst make the fire, all of them may be slid down, rendering the stove air-tight. 'lo create a draft it will only be necessary to draw out the ash-pan, so that the draft can pass through it, through the grate or tire, and through the tubes'a and holes b, as before described. After the fire has commenced to burn, I can move up all the outside slides or doors, leaving the perforated doors standing,

so that the fire will shine through them; or

all can be raised, leaving the fire exposed on all sides, and as high as may be desired to decrease the draft and expose the fire; or only one or more of the sides of the burning grate may be exposed,leaving the other sides down.

This stove has then all the comfortable appearance of a grate-lire, with much more heat. If all the doors are lifted a few inches, the stove will present a lively and cheerful appearance fully equal to a Wood-fire.

It will be seen Fig. 8 represents a hollow grate; and I intend Yto make all my grates thus, because of their convenience and durability, and for using the steam for heating purposes, and for preserving a healthy state of atmosphere in the room.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,

The arrangement .of the water-chamber N, chambers E and L' and O, pillars H, H', and H2, hollow grate, and tubes R and R', as. set forth.
